The short reign of Trebonianus Gallus and Volusianus was notable for the outbreak of a plague, which may have caused Hostilian's death, the invasion of the Sassanian Empire, and the raids of the Goths. Volusian was killed alongside his father in August 253 by their own soldiers, who were terrified of the forces of the usurper Aemilianus who were marching towards Rome. The forces of Valerian, who had stayed loyal to Gallus and Volusian, put an end to Aemilian's short reign.
